1. A medical injector comprising at least one syringe port for engaging a syringe, the at least one syringe port comprising a locking mechanism comprising:
- a housing;
a first retaining ring at a distal end of the housing, the first retaining ring having a central opening and a sidewall, wherein the sidewall has one or more first recesses extending radially outward into the sidewall and lateral surfaces of each first recess defining a travel path for guiding movement of one or more retaining lugs of the syringe; and
a second retaining ring that is rotatable relative to the first retaining ring and the housing,wherein the second retaining ring comprising one or more locking elements extending radially inward from an inner sidewall of the second retaining ring and are separated by one or more second recesses for receiving the one or more retaining lugs when an insertion section of the syringe is inserted through the central opening of the first retaining ring, wherein the one or more locking elements comprise a first inclined surface for engaging a corresponding inclined surface of the one or more retaining lugs for axially ejecting the syringe upon disengagement of the syringe from the at least one syringe port.

Abstract
A medical injector including at least one syringe port for engaging at least one syringe and having a locking mechanism. The locking mechanism enables the syringe to self-align with the syringe port for locking engagement upon insertion of the syringe into the syringe port and to axially eject the syringe from the port upon rotational disengagement of the syringe from the port.
